ABSTRACT:
A method for the design of a golf club head includes the selection, by the designer, of dimensions which define the basic shape of the golf club head. Once the basic shape of the club head is defined, critical points on the golf club head may be located. Once the basic shape and the critical points are known, a model of the basic shape may then be displayed. In addition, the method may further include the selection of desired mass properties, types of mass constraints and back-weighting parameters, all of which are determined by the designer. These specifications, in addition to the basic shape of the club head permit the design of back-weighting of the club head. Once the back-weighting has been designed, the final solid model of the golf club head, which includes the basic shape and back-weighting, may be displayed. In achieving the final solid model, the designer may employ finite element solid modeling methods, optimization algorithms, geometric influencing, and modification of the original criteria specified by the designer. The system which is used to perform the method, includes a computer loaded with a basic shape program and a finite element solid modeling program. The computer is also connected to a display. When the computer operates the basic shape program, the user-specified dimensions are retrieved and the locations of the critical points are determined. The computer then operates a finite element solid modeling program to retrieve the dimensions and critical points to then display the basic shape model. In addition, the computer includes a back-weighting program. When the computer operates the back-weighting program, the mass properties, types of mass constraints, and back-weighting parameters which were selected by the designer are retrieved and the critical points concerning the back-weighting are located. The computer then employs the finite element solid modeling and analysis program to display a final back-weighted solid model of a completed golf club head.
